> changing the extensions API to make it less powerful Changing the extensions API to decouple it from the browser's internals, allowing long-needed refactoring, a move to multiple processes, sandboxing, etc. And because the old extensions API must be completely scrapped (and ought to have been scrapped years ago), it makes more sense to replace it with a new thing that's compatible with other browsers rather than a new thing that only works with Firefox.
